Abstract

The novel branched oligosilyltriflates of formula [TfO(Me ₃Si)₂Si]₂E (2a-d) [E = 0 (2a), SiMe₂ (2b), GeMe₂ (2c), SiMe₂-SiMe₂ (2d)] and [TfO(Me₃Si)₂SiSiMe₂]SiMe (9) have been prepared by the protodesilylation of [Ph(Me₃Si)₂Si]₂E (1a-c), [H(Me₃Si)₂Si]₂E (5d) and [Ph(Me ₃Si)₂SiSiMe₂]₃SiMe (8) using TfOH (CF₃SO₃H) as reagent in almost quantitative yields. The crystal structure of 2b is reported.
